Defensive publication

ABSTRACT

A POWDER COATING COMPOSITION WHICH MAY BE COATED BY TECHNIQUES SUCH AS FLUIDIZED BED, ELECTROSTATIC FLUIDIZED BED OR ELECTROSTATIC SPRAY, COMPRISING AMIXTURE OF A POLYESTER MATERIAL SELECTED FROM POLY(NEOPENTYL TEREPHTHALATE), CERTAIN ALKYLENE COPOLYMERS OF ISOPHTHALIC AND TEREPHTHALIC ACID, AND ALIPHATIC DIACID MODIFICATIONS OF THESE COPOLYMERS, BLENDED WITH A WIDE WEIGHT PERCENTAGE RANGE OF CELLULOSE ACETATE BUTYRATE OR CELLULOSE ACETATE PROPIONATE. FUSED CATING OF THESE MATERIALS HAVE A REDUCED GLOSS AND CONTROLLABLE TEXTURE.
